1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundEvidence from randomized controlled trials published since 2004 shows that elective laparoscopic colectomy for colon cancer improves short-term postoperative outcomes with equivalent oncologic outcomes compared to open colectomy. The objective of this study was to examine the uptake of elective laparoscopic colectomy in Canada and compare its use among Canadian provinces.

methodsIn this descriptive analysis, we identified from hospital discharge abstracts all patients in the Canadian provinces (except Quebec) who underwent elective colectomy for colon cancer between 2004/05 and 2014/15. We compared temporal changes in the proportion of patients who underwent laparoscopic colectomy or open colectomy among provinces using logistic regression.

resultsOf 63 504 patients who underwent elective colectomy between 2004/05 and 2014/15, 19 691 (31.0%) underwent laparoscopic colectomy. The annual proportion of patients who underwent laparoscopic colectomy increased from 9.2% in 2004/05 to 51.5% in 2014/15 (mean annual percent increase 4.2%). There were significant differences between provinces in the overall proportion of patients who underwent laparoscopic colectomy (

interpretationAlthough the use of laparoscopic colectomy increased rapidly between 2004/05 and 2014/15 in Canada, substantial interprovincial variation exists. Further knowledge-translation strategies are needed to ensure equal access to laparoscopic colectomy for all Canadians.
